.To all whom it may concern:

Be it vknown that I, CALvIN A. SHIVE, a citizen of the United States, residing at Cherry-nale, in the county vof -liiontgomery and State of Kansas, have invented certain ynew rand ruseul Improvements in Gearing, of

jwhich the following is a specification.

'lllziis` invention relates to washing ma- A y: -ehnesandhas for its object to produce a ma- .fehineof thatoharacter embodying a mangle v-raclr mechanism, in which the movement of :the Washin drum is cushioned each time its y direction o movement is reversed in order to f fof this character of simp e,

hereinafter a pear, the invention consists in .certain nove and lpeculiar features of con- ,structionand organization as hereinafter described and claimed 3 and in order that it may be fully.-,nnderstood reference is to be had to the accompanying drawings, whichyFigure 1, is a top plan view of a washing machine embodying my invention, the cover fing drum mainly in elevation.

Fi 4, is a vertical section taken on the line I IV of Fig. 1 but showing 4 mainly the water receptacle and the ymangle 'l slot S which extends coneentricallyo'f the axisy rack mechanism. Fig. 5, is an enlarged ver- 'tical .section taken on the dottedline V of -F ig. 3 but with thezbearing screw withdrawn.

at 10, its lsemi-circular ends being toothed as shown at v11 and 12 respectively, this curved and continuous rack bar in conjunction with cog pinion 13 formingy a mangle rack for reversing the operation of the'wheel without reversing that of the pinion, and in order to properly guide the pinion, which has movement in a vertical plane, l castiwith or secure rigidly to wheel 7, a casting 14, said casting being spaced inward of the wheel as shown in Fig. 2, in order to accommodate the angular positions assumed by the pinion in the up 4and down movement referred to.

-The casting is provided with a curved slot arranged concentrically of the axis of wheel 7 and centrally of the slot of the latter, the inner wall of said slot being numbered 15 and the outer Wall 1o, and the curved ends 17 and 18, and said slot is subdivided into the inner groove 19 and the outer groove 20, by the concentric partition wall 21.

y 22 indicates a casting secured to the front wall of the receptacle above the axis of wheel 7 and provided with a chamber 23 and journaled in said casting is a short shaft 24 universally joined as shown at 25 to the short or tumbling shaft 26 on which the pinion 13 -is rigidly mountedso as to be capable of engaging the rack'teeth 9, 10, 11' and 12, the pinion -being compelled to engage said teeth ecause oi the enga rement of the inner end of the tumbling sha 't with the grooved casting 14, the enga ement of the inner groove 19 with said sha t oausin the pinion toengage the teeth 9 for the fu l=length of the said series of teeth, when assuming the pinion is rotating in the direction indicated by the arrow a Fig. 4 said shaft rides up on the rounded end Wall 17 and into theouter groove 20 of the casting, this movement of the shaft compelling the pinion to ride upward on the end teeth 11 and engage the outer teeth 10. As the pinion travels upward in engagement with .teeth 11, wheel 7 1s practically stationaryand as it engages the lteeth 10, wheel 7 is rotated in the direction indicated by the ar row l) Fig. 4, this movement continuing until said Wheel has made almost a complete revolution when the `opposite end ofthe slot and grooves 19 and 20 are vertically above their axes of movement. The pinion then travels downward in engagement with teethv12 and its shaft moves from the outer groove 20 'into the'innerggroove ,19; It will thus` be seen that under vthe continuous operation of the 'pinion in one direction wheel'7 will rotate' iahnost complete revolutions in opposite directions i alternately.

The tumbling shatmay be driven by means of the hand wheel 27 or by a belt wheel '28 or its equivalent, the hand wheel' being adapted to use on household machines- I and the ,belt for use in laundries where electric or other power is' available.

To reduce to the minimum the friction between the tumbling vshaft and the grooved casting 14,- the former is referably provided With an anti-friction rolllerv 29 andto guide vthe'itunibling shaft in its vertical movement and 'prevent' it from moving laterall itis equipped with a'box 30 arranged to side be- 31, set in the receptacle,said box being pro- 'vided with laterally projecting flanges 32 20 tween curved` guide ribs of a slotted casting bearing against the convex l`side ofthe. uide ribs so as to receive' any outward end t rust ofl the' tumbling shaft which might tend to effect disengagement between vthe pinion and `the manglerack.

The ear wheel 7 meshes with a small ear 33 rigidly secured 'on the longitudinal s aft 34' journaled at one end in a bearing 35'and at the other in abearing 36 carried by the receptacle, and -ournaled on said shaft is' bevelgear 37 secure rigidly to one end of a sti helijcal incased s ring 38 surrounding and rigidly secured to t c shaft at one endthrough the w medium of a collar 39 secured on said shaft. The bevel gear meshes with a large bevel gear 40 rigidly s'ecuredvonl one of the trunnions 41 projecting Afrom thev opposite ends of a `perorated washing drum 42, said drum being provided with a suitable door-closed opening 43 through'which the work is insertedl and re- .moved, the door being adapted to be securedl its closed position durinCr the washing .operation through'any s'uitabble fastening.

The ltrunnions are rovided with conical )recesses 44 andwhen t e drunijis iirst placed 'in the receptacle;v they:v yrest' on lthe recessed ,shelves 45with the axes of the trunnion recesses 44` slightly below the conical-pointed' set screws 46 adjustable in the castings'of l which the shelves 45 form a part7 so that when said set screws are screwed home their conical ends will enter the eccentrically disposed recesses 45 and raise the drum until its trunnions are out of frictional contact with the shelves 45, the raising of the drum .incidentally throwing wheel 40 into engagement with pinion 37 so that the reversin action of the gear wheel 7Y shall be imparte to the perforated drum. As each reversing movementA of the mangle rack occurs the spring 38 yields so as to cushion the arrest o the drum instead of bringing it to an abru t and sudden sto which would not only e destructive to t e machine but also increase the labor of a erson turning Wheel 27 by hand. `It will t us be seen that the i drum is reversed without any injurious shock or jar, it being understood of course that vthe speed of the drum will be greater when the pinion 13 is engaging teeth 9 than when it is engaging teeth 10, but that such difference in speed will be hardly perceptible to one observing the machine. i

As the drum is revolved the water standing in the receptacle to the required depth pours in and out through the perforations of -th'e drum, which action of the water in conjunction with the rubbing of thel clothes by the roughened interior of the drum serves to effect a thorough and expeditiousl cleansingrr operation.

.In Fig. 3, certain parts are arranged in 'dierent positions from those they occupy in Fig. 1, that is to say, the drum is shown as arranged with its axis in longitudinal alinement with bolt 6, one of the trunnion cavities being mounted on thepointed end 47 (see Fig. 2) of said bolt, the other trunnion being journaled on set screw 46, it being understoodA that in this rearrangementA the casting carrying the last-named set screw vwill be vsecured in the rear end wall of the receptacle, as -indicated in Fig. 3. In this construction', the drum instead of being provided with'a bevel gear 40 will be provided with a peripherally-toothed'gear 48 `meshin with a pinion 49, employed in lieu of beve gear 37, and the last-named gear will be journaled 'on a lon shaft 50 employed as al substitute for the s ort shaft 34, the bearing bracket 36 being shifted in the rece tacle to accommodate. the long shaft. T e same spring A38 and collar 39 will be employed as a Aconnection between the pinion 49 and the shaft f50, in order that each reversing action ofthedrum shall be cushioned as hereinbefore explained with reference to the construction shown in Fig. 1. A machine of the type shown in Fig. 3`is peculiarly adapted for use in a steam or lotherp'ower laundry..

From the above description it will be apparent that I have produced a washing machine possessing the'features of advanta e enumerated as desirable and I Wish it to e understood that I do not desire to be'restricted to the exact details of construction shown and described,` as modifications which are not a departure from the principle and versally joined at one end to the driving said gear Wheel, a Wheel journaled on said shaft, a spring rigid at its opposite ends with .said shaft and the Wheel journaled' thereon, 15 shaft, and having its opposite end playingfin and a driven member carried by the support the grooves of said castingl a pinion rigid on* and'geared to said Wheel. said shaft engaging the teeth of said curved In. testimony whereof I aflix my signature spt in tlel: gearhwieel, adboxing j ourifialed o3 in the presence of two Witnesses.
